VENTILATED SUNSI-IADE.

Application iled May 7,

the provision of `simple means associated with the shade for enabling' effective circulation of air through and behind the shade without permitting the passage `of sunligl'it therethrough at an Objectionableangle. My invention when embodied for instance in a window awning permits the passage of air through the awning and its entrance into a room through the upper portion of the window whether the shade be in the iiiclined position usual with window awnings or hanging vertically as a porch protector, itr may be mounted and raised and lowered K by the usual supporting and Operating means.

I effect the characteristics above mentioiied by providing a series of openings across the awning and arranging a -panel or flap behind each opening, which `panel is su'iciently large to prevent the entrance of sunlight at an objectionable angle, but `inay be readily moved by the air. Moreover, these panels ,are 'spaced sufiiciently from each other to permitindependent movement, and at the same time to permit the ent ance of air therebetween for effecting adequate ventilation behind the awning.

The preferred means for carrying out my invention will be set forth in the following description which pertains to the accompanying drawings. The essential features of my invention will be summarized in the claims.

In the drawings, Fig. l is a perspective view of a window awning embodying my invention; Fig.` 2 is a rear view showing the panels in place; Fig. 3 is a vertical trans- 0 verse section through the awning shown in Fig. 1; Fig. t is a perspective view of an awning embodying' my invention when used as a vertically disposed shade; and Fig. 5 is a fragmentary view of the awning adja- 1923. serial No. 637,153.

cent the opening shown in Fig. 4 to indicate the manner in which tlieopenings may be reinforced and in wliiclrthe panels may be attached to the shade. i

`Referring to the accompanying drawings byreference numerals, 1 indicates the face of an awning or sun shade having vertically disposed sides 2. This awning has the usualv guide brackets 3 and frame 4 which may be` raised by hoisting ropes in the customary manner.

To provide a simple and effective means for Ventilating theV space behind ther awning, I have shown a series of openings l0 in' one row, and a series of openings 11 in another row. These openings are preferably staggered and are spacedzsuiciently apart to permit the passage of air therethrough, and at the same time to provide adequate material between the openings to prevent the awning from,beingwealened In the preferred embodiment eachbpening is narrow at the top and wider at ,the bottom asl illustrated, 'so as. to permit the use of panels which have spaces between them toy enable the free passage of air beyond theY By bringing the material together flaps. p at thetop vof the opening, the body ofthe awning is not weakened as would be the case were the openings as widefat the top as at the bottom.v T l Y The panelsv or flaps illustrated comprise fabric shields l5 which are placed beh-ind the openings 10, and are securely aiixed'at one end thereof'to theA awning, as by sewing, directly above the opening'. Similarly, I provide l'laps 1G which are atiixed to the awning above the openings 1l. Thus each Hap hangs vertically and is spaced sufliciently from the adjacent iap to permit the passage `,of air therebetween. Each flap, however, is larger in area than the associated Opening wherefore the entrance of objectionable light rays is prevented.

` By the described arrangement airv passes freely through the awning while the direct rays ofthe sun do not. Moreover, when the air within the region of the awning is set` in motion, the currents of air' flowing through theopenings and striking the flaps will be thereby deflected, and if these currents are sulficieiitly strong the iiaps lwill be caused to vibrate and will` thereupon cause the air to be deflected over a wider region, the result being a thorough dissemination and circulation of the air.

My invention is valso'V Well 'adapted foiruse on a vertical'awning or sun shade as illustrated iii Fig. el, wherein the openings-1()a and 11 are provided-with suitable naps-15aan'd 16a respectively. The openings preferably are staggered as illustratechand each; flap is independently movable as heretofore explained. i

The preferred manner of attaching 4 the fiaps'etothe awning or'fshade `is shown in' Fig. 52,5 Iwherein fthe opening is reinforced by abinding, such asrafta'pe tlwhich'extendsl around the marginal edges ofthe-openings,

the-two ends 21 and 22 lying close tof each other atthe/top as: shown, and ea'cliflap has a'binjdingfQlaboutits margin; The upper edge'ofthepanel 15C and its binding' are preferably interposedbetweenthe overlapping kedgesof the .body portion ofthe awning asat 15d, and a transverse binding strip'23'-on: the outer' face of the awning may be 'eniployedio' fasten" the lappedy edgesv tolthe'panel asby stitehingQlf The binding strip:28`tliusactsy as areinforicing meniber as' well` as 'a covering' for vthe 'rough edges atthe ends' ofthe inarginal'bindings.

Fromk the foregoing description it will*v be Vseeirthat my invention provides a device which is well adapted for a 'sun shade, so`

as to permitk thev circulationl of;` air 'through it` without admitting objectionable light rays; imoreover', the flaps "are independently movable andare spaced' sufficieiitlyV from yeachother.sothat air-passing through the openings' may circulateI behind l'the Vawningf and enter `thev roo'mor porch shaded byithej awning. Moreover', so perforati-ngrY the f body of the awning, .I have provided against sudden' gustsA of wind tearing itl from the building.H j

The rays of sun 'beating down upon an ordinary awning `heats Vthe air "pocketed `beneathit',=and thus suchian4 awning in front of' an open window, acting as ka collector ofv heat, heats the adjacent air Within the room, though shielding froin"`tl`ie directrays;4 I have provided-an awningY which vfunctions asi an` ordinary awningjin' breakingi the'di-v rect raysv ofthe sun,Vv Whilein addition I have provided acoolin'g and Ventilating effectby causing the awningto-.act very much in the same manner as doA theleaves on a tree.

1. Inal device ofthe class fdescribed, the combination ofa fabric shade having a series of' separated openings therein',l and a seriesof fabric flaps' securely'aiiixedto the shade above the respective openings Vand ydepending behind thein,.said flaps beingindep endeiitly` movable and being' spaced apart"suiiicientlyA to-perinit'the passage' of air between ladj aeentflaps.

2. In 'combinationJ an awning having a row of spaced openings therein, of flaps attached to the-y awning' respectively above each opening, each of said flaps having an area larger thanthe area of the associated openng, said -flapsw being.y nearly contiguous but each being so shaped that a passageivayfis 'provided between adjacent flaps for the passage of air, whereby free circulation of the air is obtained behind the awning.

3. In combination, an awning having a lseries of opeiiingsth'ei'ein, each opening being `narrower at thetop than Yat thebottoin, a flapsecurely'fixed to the awning directly behind each ofsaid openings, said flaps having an area larger than that of the-'associated openings*a and having such shapefthat` the lower' portions are iii-close proxiinityso as to provide a shield for the rays of thesun passing through the opening, while'the upper portions of the flaps are spaced salti#- eiently apartto provide passageway's for the free circulation of-air behindy the awning,

li'In coinbinationpan awning having a fabric sheet witha plurality of spaced openings1arranged-in rows, thelopenings in oner row being staggered-with relation to those in an adjacent row, and fabric flaps securely, fixed at theirupper edges tothe baclof the awning behind the openings, said flaps being independently movable to allow the passage of airbetween them while providthrough the openings.`

5./ In combination, anl awninghaving a ing a'shield for the rays of the sun passing'v plurality of spaced openings arranged in rows, the-openings-in onerow being stag,-v gered with relation to those in an adjacentv row', fla-ps securely fixed to the awning adrower 'at the-top thanjat the bottoni, and being .so spaced yas to be independently movable, they bottoin--portions'-of the flapsbeing in 'close proxiinityto each otherto provide sliicldfor -the rays of the sun passing through the openings while the 'upper extremities are spaced sufficiently apart to provide fa passageway forgthe freeY circulation of air behindI the awning.
